INVENTOR KURT R. KEYDEL IATTORNEYS Patented Oct. 3, 1939 UNITED STATESea'rENr oFFICE 5 Claims.

The present invention relates to mops or brushes and more specificallyto mop head and handle structure.

Among the objects of the invention is a mop head and handle structure inwhich the mop head, though irmly held to the handle for use, is easilyremoved for the purpose of substituting therefor a new head.

Another object is a structure of the kind indicated in which thecooperating parts of head and handle are simple, inexpensive, effective,and not easy to get out of order or adjustment.

Another object is a head and handle structure in which application ofthe head to the handle is a simple push in operation, while the removalis a simple pull out operation, yet there is little or no possibility ofthe head becoming detached during use.

Still other objects and advantages will readily occur to those skilledin the art upon reference to the following description and theaccompanying drawing in which Figure l is a perspective view of the mophead and handle assembly.

Figure 2 is a central longitudinal section through the connecting means.

Figure 3 is a perspective View of a detail.

Figure 4 is a section on line 4 4 of Figure 2.

Figure 5 is a partial longitudinal section at right angles to the planeof section of Figure 2.

As indicated in the drawing, the mop assembly consists of a headportion, designated by the numeral IU, and a handle portion, designatedby the numeral 20, the head portion comprising strands of mop materialII, which, for example, may be oil impregnated strips of paper, a bundleof which is tightly encircled by a heavy wire I2, having its endstightly and substantially uniformly twisted together as at I3 to form acorrugated shank, and having the wire ends I3a extended a short distancein the same plane but separated, so as to form in effect a iiat tongue.

Instead of the smooth strands of mop material II as illustrated, thesestrips may be of paper which has been crinkled or crimped so as toproduce a uliness in the finished mop.

'Ihe handle portion 20 comprises a handle proper of wood or othersuitable material with a longitudinal axial bore 2| in one end of adepth somewhat greater than the length of shank I3 of the head.

Fixed within bore 2| of the handle is a spring grip member 22substantially of the form shown in Figure 3, this member being formed ofa narrow strip of stiff spring metal bent back upon itself to produce arelatively flat bend or loop 22a of a width slightly greater than thethickness of the wire ends i3d. The strip is also sharply corrugated asshown at 23 to produce sharply anguiar ridges spaced to conformsubstantially 5 with the pitch of twist of the shank I3 while the armsof the U-shape spring thus formed are spaced from each other a distancesomewhat less than the overall thickness of shank. The strip is likewiseprovided with suitable barbs or claws 24 by means of which it may befirmly anchored within the bore 2|. If the handle 20 is of wood, asuitable ferrule 25 may likewise be used.

With the structure as described and properly proportioned, the shank I3when thrust into the bore 2l between the two side portions of springelement 22, will be held iirmly and maintained in place by the anglesthereof, dropping between the flights of the twisted wire, and whenthrust in until the ring I2 is close to the ferrule 25, the tongueformed by the wire ends I3a will lie at within loop 22a and preventrotation and possible unscrewing and detachment of the mop head.

While the spring member 22 is shown as a U-shaped member of fiat stock,it is obvious that any form of spring member having projecting portionsthat cooperate with a shank such as shank I3 may be used and indeed suchother forms are contemplated. 30

This application is a continuation n part of application Serial No.123,322, led by the same inventor February l, 1937.

Now having described the invention and the preferred embodimentsthereof, it is to be understood that said invention is to be limited,not to the specific disclosure herein set forth, but only by the scopeof the claims which follow:

What I claim is:

1. A mop head and handle construction consisting of a mop head providedwith a corrugated shank portion and a handle having an axial bore, astiff corrugated spring member xed within the bore, the corrugations ofthe spring member conforming to the corrugations of the said shankwhereby the ridges of the one fall between ridges of the other tothereby maintain the shank within` the bore when thrust thereinto.

2. In a mop head and handle construction a mop head provided with acorrugated shank, and a handle therefor having an opening into whichsaid shank is adapted to be thrust, a spring member within said opening,said spring member being U-shaped and of at corrugated 55 metal, withthe spacing of the corrugations conforming to the spacing of thecorrugations of the shank, and said shank having two arms spaced fromeach other a distance somewhat less than the overall thickness of saidshank.

3. In a mop head and handle construction a mop head comprising a bundleof mop material encircled by a stiff wire the ends of Which are twistedtogether with a substantially uniform pitch, and a handle provided withan axial bore for receiving said twisted ends, a spring Within said boresaid spring being of iiat corrugated metal, the corrugations of saidspring being spaced to conform to the iiights of wire in the twist, andbeing sharply angular upon that side of the spring adapted to contactsaid twisted wire.

4. In a mop head and handle construction a mop head comprising a bundleof mop material encircled by a stiif Wire the ends of which are twistedtogether with a substantially uniform pitch, the extreme ends of saidwire being eX- tended a short distance in the same plane to form a attongue, and a handle provided with an axial bore for receiving saidtwisted ends, a spring within said bore said spring being of flatcorrugated metal provided with a loop portion adapted to receive saidtongue, the corrugations of said spring being spaced to conform to theflights of Wire in the twist, and being sharply angular upon that sideof the spring adapted to Contact said twisted Wire.

5. A mop head and handle construction consisting of a mop head having ashank of twisted wire, a handle having a socket into which said shank isadapted to be thrust, a resilient member in said socket said resilientmember having projecting portions forming in effect a receiving threadfor the iights of the twisted wire shank, and means for preventingrotation of said shank when fully thrust into said socket.
